For Bobby Darin, performing was his life. It kept his heart beating. He came alive onstage, even when he was near collapse offstage. From the age of seven, Walden Robert Cassotto--Little Bobby knows the odds are stacked against him. Rheumatic fever has permanently damaged his heart, and he's not expected to make it to age fifteen. Bobby's family pour all their energies into caring for him. Bobby's frail heart may be one truth, but his mother Polly, a former singer, introduces her boy to another wonderful truth: music. Music becomes Bobby's bargaining chip against time; he's not only singing, but also playing piano, drums and guitar before he even hits his teens. Music takes him into a world beyond the Bronx, and beyond sickness. It's a world of effortlessly swinging songs, and couples dancing to the lilt of Bobby's voice. Bobby has a plan, and no heart ailment will stop him.
